Now I have solved all such problems. By moving the game to another SSD, it can be said that all the problems that occurred were caused by my own SSD. Therefore, I would like to thank Mr. Geez for taking care of the problems that occurred. Thank you very much. You can now close this ticket.

Now I've followed Mr. Geez's advice, but it still doesn't seem to help with the lag or freezes. Moreover, the symptom of not being able to render texure is not just the trees. But there are some items in the game. If you have any further suggestions please help. Thank you very much.
